Abstract
Abstract A removable chuck has a chuck member for holding a drill bit. Also, a mechanism is coupled with the chuck body to retain the chuck body to a drill spindle. The retention mechanism, in a first position, a biasing member in a non-biasing condition, retains the chuck on the drill spindle and in a second position, with the biasing member in a biased condition, the chuck is enabled to be removed from the spindle.
